Important:
High Voltage adjustment should
NOT be adjusted in field. This is
adjusted at factory using precise
loads and should NOT
be
readjusted.
1.4 High Voltage Adjustment (should NOT be
readjusted in field).
Adjustment preparation
(1) Connect High Voltage meter to FBT High Voltage
output. Connect GND of High Voltage meter to CPT
GND or FBT GND.
(2) Check that High Voltage adjustment VR (RH17) is
set to mechanical center. (located behind FBT on
DEFLECTION PWB).
(3) Receive circle pattern signal.
(4) VIDEO control should be reset.
Adjustment procedure
(1) Adjust High Voltage to following spec. by turning VR
RH17 slowly. ADJ. SPEC =
31.7±0.2kV(DP17),
= 30.2±0.2kv(DP14G).
(2) After adjustment, fix VR RH17 with Silicone glue
(KE40RTV).

(2) Push “SERVICE ONLY” SW on CONV. FOCUS
PWB. (Enter to DCU ADJ. mode).
(3) Push HELP key on R/C. (Green cross hatch is
displayed).
Then push EXIT key on R/C. (Character pattern
is displayed. This is the PHASE setting mode).
(4) Set PH-H phase data as shown below by using
4 and 6 key on R/C.
(5) Set PH-V phase data as shown below by using
2 and 5 key on R/C.
(6) Set CR-H phase data as shown below by using
THUMB STICK
and
key on R/C.
(7) Set CR-V phase data as shown below by using
THUMB STICK
and
key on R/C.
(8) Push HELP key on R/C to exit from the PHASE
mode.
(9) Push PIP MODE key 2 times on R/C to write the
phase data to memory.
(10) When Green dots are displayed, push MUTE
key to return to DCU ADJ. mode.
(11) Push “SERVICE ONLY” SW to return to RF or
VIDEO mode.
